Also, they started promoting the episode like 2 or 3 weeks before, every single day articles and promotion about it, people at certain point were tired of that and didn`t tune in, after getting 3 weeks of articles and stuff, they should have done what they always do with episodes, not give the plot away, so people were like, so this will have Cs wedding and the characters, so nothing huge in terms of developing story about the villain to see.
The musical episode should have been in the episode 100, like a special episode before starting the UW things and the wedding should have been only in end , really end of the series, like last minutes and then would end with everyone happy.
Let`s see how 3 hours of OUAT will work this week, like specials talking about things the viewers already know, bc they done lots of specials like that one, and 2 hours of confusion, without people knowing if they are watching the series or season finale, Oh, yeah, this wont end good this week as well.
